One of the most feared predators in the ocean is the great white shark. Although it is known that the great white shark grows to a mean length of 21 feet, a marine biologist believes that great white sharks off the Bermuda coast grow much longer because of unusual feeding habits. To test this claim, researchers plan to capture a number of full-grown great white sharks off the Bermuda coast, measure them, and set them free. However, because capturing sharks is difficult, costly, and very dangerous, only three are sampled. Their lengths are 24, 20, and 22 feet. Do the data provide sufficient evidence to support the marine biologist's claim at α=.05?

Question 5
Part A In order to estimate the mean length of a great white
shark. A researcher is only able to gather a sample of three great
white sharks, but knows that the lengths of great white sharks is
normally distributed. The three sharks have lengths of 24, 20 and
22 feet. Find the 99% confidence interval for the mean length of a
great white shark. Round to two decimal places.

Sigmund Freud, although one of the best-known personality
theorists, is probably also one of the most controversial in the
field of psychology. When starting to consider theories of
personality, one must begin with a look at Sigmund Freud, as he was
one of the first theorists to develop a psychoanalytical theory
that was based on real-life patients and not studies conducted in a
lab. Even if you do not agree with his theories, he is the starting
point from which...
